Abstract

A new RuO₂-Co₃O₄@g-C₃N₄ ternary nanocomposite was produced to remove ciprofloxacin (CIP) from the aqueous solution. Characterization was conducted using XPS, TEM, FTIR, SEM, and XRD techniques. The adsorption capacity of RuO₂-Co₃O₄@g-C₃N₄ nanocomposite for CIP was examined utilizing a batch experimental approach under several constraints. The findings indicated that maximum adsorption capacity of CIP was achieved during a contact period of 22 min for an adsorbent dose of 0.4 mg/L, under optimal conditions of pH 7 and temperature of 25 °C. Analysis of thermodynamic parameters indicates that ΔG° and ΔH° are negative. Consequently, the adsorption occurs spontaneously, exhibiting an exothermic character. The adsorption isotherm curves matched the Langmuir model more closely than the Freundlich model (R² = 0.993), Dubinin-Radushkevich (R² = 0.887) and Temkin (R² = 0.993). The adsorption kinetics graphs matched the pseudo-second-order model (R² = 0.945). RuO₂-Co₃O₄@g-C₃N₄ nanocomposite exhibits a maximal adsorption capacity of 146.66 mg/g at optimal pH = 7. FTIR and pH analyses were used to clarify the adsorption mechanism. The research indicates that RuO₂-Co₃O₄@g-C₃N₄ nanocomposite possesses significant potential for the large-scale elimination of CIP in wastewater treatment.

期刊介绍： DRM is a leading international journal that publishes new fundamental and applied research on all forms of diamond, the integration of diamond with other advanced materials and development of technologies exploiting diamond. The synthesis, characterization and processing of single crystal diamond, polycrystalline films, nanodiamond powders and heterostructures with other advanced materials are encouraged topics for technical and review articles. In addition to diamond, the journal publishes manuscripts on the synthesis, characterization and application of other related materials including diamond-like carbons, carbon nanotubes, graphene, and boron and carbon nitrides. Articles are sought on the chemical functionalization of diamond and related materials as well as their use in electrochemistry, energy storage and conversion, chemical and biological sensing, imaging, thermal management, photonic and quantum applications, electron emission and electronic devices. The International Conference on Diamond and Carbon Materials has evolved into the largest and most well attended forum in the field of diamond, providing a forum to showcase the latest results in the science and technology of diamond and other carbon materials such as carbon nanotubes, graphene, and diamond-like carbon. Run annually in association with Diamond and Related Materials the conference provides junior and established researchers the opportunity to exchange the latest results ranging from fundamental physical and chemical concepts to applied research focusing on the next generation carbon-based devices.
